A candy store that only appears when you need it. Beniko knows exactly what you came for before you do, hands you something that looks innocent, and leaves you holding the answer to a problem you didn't know how to ask about. The catch is always the same: the cure works perfectly, but only if you're brave enough to actually use it the way it demands.

Zenitendou is a strange candy store, and only people with luck on their side ever manage to find it. Beniko, the shopkeeper, recommends sweets to each visitor, and every one she picks fits that buyer's particular trouble exactly. Whether a candy brings happiness or misfortune depends on whether the buyer uses or eats it the right way. The series is a mystery told in short episodes.
